Designer drugs, or new psychoactive substances (NPS), are synthetic chemicals that mimic the effects of classic drugs of abuse. There has been an alarming worldwide increase in the abuse of NPS in recent years. NPS are cheap, easy to obtain, and often legally available. In this volume, leading experts summarize the latest studies regarding the molecular mechanisms of action, behavioral effects, and adverse consequences of popular NPS. Specific chapters clarify the differences between various types of NPS, namely: stimulants, cannabinoids and hallucinogens. Thus, this volume broadens our understanding of NPS and provides insight into the rapidly evolving “new drug” phenomenon.

This book is a printed edition of the Special Issue "Recent Changes in Drug Abuse Scenario: The Novel Psychoactive Substances (NPS) Phenomenon" that was published in Brain Sciences

An increasing number of novel psychoactive drugs are currently available and sold as 'legal highs' or 'research chemicals'. These New Psychoactive Substances (NPS) constitute a broad range of hundreds of natural and synthetic drugs, including synthetic cannabinoids, synthetic cathinones, synthetic opioids and other classes, which use has resulted in a significantly growing number of intoxication and mortality, as reported by emergency and poison centres from all over the world. Definition of “NPS” includes any substance that has recently become available and has been designed purposely to replace illegal drugs, although not necessarily of new synthesis. Use of NPS is dramatically increased in the last decade and represents a serious risk for the public health. Their ever-evolving chemical structure, the possibility to distribute in real time through the Internet and social networks information about their use and effects have dramatically challenged public health and drug policies internationally. NPS recently attracted great attention, but most are still unregulated and proposed online as legal alternatives to traditional illicit drugs. Unfortunately, this area is still poorly investigated and very limited information are available so far on their nature and potential risks. The phenomenon of NPS requires multi-national and multi-disciplinary collaborations to improve our knowledge on this changing drug market, to share information and define good practices at a global level. Political and educational efforts are indispensable to regulate this mutable scenario and to inform the public about health consequences of NPS use. Clinicians and emergency staff should be aware that NPS may cause severe health consequences and unexpected adverse effects, and be informed on how to recognized and treat specific intoxication cases. Considering the widespread use of NPS and paucity of information about their toxicology and pharmacology, this Research Topic will be useful to understand the new trends in the scenario of drug use, abuse and addiction to inform professionals and general public about the health problems caused by NPS and to help drug-control policies to adopt suitable control measures.

This volume is designed to feature the pharmacology of new psychoactive substances, legislative aspects, information exchange including epidemiology, and clinical, forensic, and analytical toxicology in order to facilitate the understanding of this complex and rapidly developing phenomenon.

In this book, Murphy brings together a team of international experts to review cutting-edge scientific literature from the field of psychobiology and related disciplines which addresses important questions and broadens our understanding of substance use behaviours. The reader is introduced to the multi-faceted nature of substance use and misuse, and its growing need to be discussed across diverse disciplines and perspectives. The book also addresses important questions regarding public policy and professional practice in the context of different social and cultural environments, and comments on the methodological and ethical issues in substance use and misuse. Chapters explore a spectrum of substances, which include: cocaine, alcohol, ecstasy (MDMA), methamphetamine, synthetic cannabinoids, tobacco, ketamine, novel psychoactive substances, and vaping products. The use of these substances poses important questions for science and for society. This book is written to help academics, practitioners, and students in a variety of academic and professional disciplines answer those questions while staying up to date with the psychobiological literature. This is a vital resource for professionals and upper-level undergraduate and postgraduate students undertaking research in areas related to biological psychology, biology, health studies, and medicine.

There are global concerns about the proliferation and misuse of club drugs and novel psychoactive substances, yet we know little about their harms and research on clinical management and treatment remains limited. This book fills the knowledge gap by providing a detailed overview of the research evidence available to date. The book provides a framework that allows readers to understand this large number of new drugs, using classifications based on primary psychoactive effect. Within this framework, the book provides detailed reviews of the more commonly used drugs. Each chapter explores pharmacology, patterns and mode of use, acute and chronic harms, and clinical interventions supported by research evidence. An invaluable resource for clinical staff, this book will support clinicians working in the emergency department, substance misuse and addiction services, mental health services, primary care, sexual health services and more. It will also be of interest to academics and those developing drug policy.

Substance misuse and addictions are a public health issue. They affect the well-being of each community and nation as a whole. It is, therefore, necessary to identify, educate, and treat individuals who are addicted to substances. Policies and procedures go hand-in-hand with public health education and safety. The science behind the public health issues of one drug may be applicable to other drugs as well. However, marshalling all of the aforementioned information into a single source is somewhat difficult due to the wide array of material. The Editors address this by compiling the research in this single reference work that serves as a "one-stop-shopping" approach to everything readers need to know about the scientific basis of public health and addictions and agents of misuse. Apart from active agents that have a plant or chemical basis, there is a need to consider that there are other forms of addiction which may have common modes of causality or prevention. These include food addiction, gaming, gambling, and other non-drug addictions. These types of addiction may be related to the addiction of drugs. The Handbook of Substance Misuse and Addictions: From Biology to Public Health offers a holistic understanding of the relationship between public health and substance misuse. The text provides a common platform upon which other forms of addiction or substance misuse can be understood and treated. Addiction processes involve understanding the biological processes as well as behavior, psychology, sociology, and public health, all of which are interlinked. This Handbook is a useful reference for lecturers, students, researchers, practitioners, and other professionals in public health, addiction science, epidemiology, health education, health promotion, and health sciences.

This book addresses how to estimate substance use and thereby evaluate policies intended to reduce the harms caused by drugs and other substances. Wastewater analysis (WWA) can provide efficient, affordable, fine-grained and objective data on population substance use trends on a very large scale. The authors discuss the potential implications of WWA as a new method for understanding substance use in a variety of settings and ignite a discourse with policy makers, criminologists, epidemiologists and other disciplines about the need for collaboration with WWA scientists. The book also features an explanation of the costs and harms of substance use with academic literature from criminological and epidemiological sources and reports from lead agencies. Additional features include: Details on the origin of wastewater analysis in environmental science Description of analytical chemistry methods for tracing a wide variety of substances, including illicit drugs, alcohol, tobacco and other chemicals Exploration of the major empirical problems in estimating population consumption of alcohol, tobacco and drugs at the international and national level Examination of the principles of human research ethics and their application to wastewater analysis Wastewater Analysis for Substance Abuse Monitoring and Policy Development is a valuable tool for analytical chemists, wastewater scientists and criminologists, as well as researchers and policy makers across disciplines who work in drug sectors.
